JOHN NAZEL, PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO SANITARY PAPER BOTTLE COMPANY, OF WILMINGTON, DELAWARE, A CORPORATION OF DELAWARE.

TUBE-WINDING MACHINE.

ToaZZ whom it may concern Be it known that I, JOHN NAZEL, a citizen of the United States, residing in the city of Philadelphia,county of Philadelphia, and State of Pennsylvania, have invented certain Improvements in Tube-Winding Machines, of which the following is a specification.

My invention is a machine for winding blank sheets to form the tubular bodies of receptacles, and it is designed for coating with an adhesive a part of the sheet that is to form the outer laminae of the tube.

The characteristic features of my improvements will fully appear in the following description and the accompanying drawings in illustration thereof.

In the drawings, Figure 1 is a sectiona. side elevation of my improved machine viewed on the line 1-1 of Fig. 2; Fig. 2 is a plan View of the machine with parts broken away for the purpose of showing interior details; Fig. 3 is a sectional view taken on the line 33 of Fig. 2; Fig. 4 is an end elevation of the machine; Fig. 5 is a sectional View showing the face of the clutch; Fig. 6 is a longitudinal sectional view showing details of the mandrel on which the tubes are wound; Fig. 7 is a longitudinal sectional view of the mandrel taken on the line 77 of Fig. 8; Fig. 8 is a sectional view taken on the line 8-8 of Fig. 6; and Fig. 9 is a sectional view of the paste roller and coacting parts taken on the line 9-9 of Fig. 2.

The machine, as shown in the drawings, comprises the frame 1 having the bearings 2, 3, and 4. A shaft 5 is journaled in the bearings 2 and 3 and has connected thereon by the spline 6 a longitudinally movable collar 7 revoluble in the bearing 4.

A mandrel 8 is engaged to the shaft 5 by a pin 9 which passes through a slot 10 and is longitudinally movable toward the hearing 4 against the action of the coiled spring 11, which has one end engaged to the pin 9 and the other end fixed to the bolt 12 held by the button 13, the latter engaging the end of the shaft. The inner end of the mandrel is provided with the bolts 14 which are longitudinally movable therein, the bolts having projections 15 adapted for ejecting a tube from the mandrel. The bolts are held normally in the position shown in Fig. 6 by springs 16 and are pushed back to eject Specification of Letters Patent.

tubes by contacting with the bearing 4 upon the longitudinal movement of the mandrel hereinafter described. A longitudinally disposed lip 17 is fixed to the mandrel and a wedge shaped bolt 18 is movable longitudinally within the mandrel through the longitudinal movement of the collar 7 to which it is fixed,'the wedge coacting with the lip to engage and disengage a blank sheet 19 to be wound on the mandrel.

A sleeve 20, journaled on the shaft 5, has fixed thereto a gear wheel 22, which drives the gear wheel 23, fixed on the shaft, through the differential speed changing gear wheels 24- and 25, the latter wheels being fixed together and journaled on the arbor 26. The shaft 5 revolves a pinion 27, which is fixed to the collar 7 and revolves a pinion 28 ournaled in the bearings 29, the pinion 28 having the beveled gear 30 fixed thereto. A shaft 31, journaled in the bearings 32, is revolved by having fixed on one end thereof the beveled gear 33, which engages the bev eled gear 30. On the other end of the shaft 31 is fixed the beveled gear 34 which revolves a beveled gear 35 fixed to the shaft 36 of a roller 37, the shaft revolving in bearings 38 and 38 on a paste tank 39 containing the roller.

A cover 40 on the tank provides a table for supporting the end of the blank sheet 19 which is to be drawn, by the revolution of the mandrel in the direction of the arrow thereon, oppositely to the direction of revolution of the roller. The sheet is held down upon the roller by the presser bar 41 during the application of the adhesive to the section which is to be wound on the inner lamina of the tube, constituting the first turn of the blank on the mandrel, the bar being elevated while the winding mechanism is at rest and lowered during part of the winding operation. The presser bar is fixed as an arm to the slide 42 which has fixed thereto the yoke 43 movable on and guided by the bearing 38. A cam 44, fixed on the revoluble shaft 36, engages the yoke to elevate the bar during part of the revolution of the shaft. The bar is lowered and held down by gravity and the action of a spring 45 during the application of the adhesive to the sheet, the spring having one end fixed to the slide 42 and the other end fixed to the stationary pin 46. A shaft 47, journaled in the bearings 48 of the tank, has thereon the fingers 49 adapted for lifting the rear end of the sheet off the roller when the presser bar has been elevated. This shaft is revolved and the fingers thrown up by a coiled spring 50 which has one end fixed to the tank and the other end attached to the arm 51 fixed on the shaft. A bracket 52 on the slide 42 engages the arm 51 and holds the fingers down while the presser bar is down, the fingers rising with the presser bar through the action of the spring. The purpose of lifting the rear end of the sheet is to avoid coating the sect-ion to the end and prevent paste from exuding in winding. A doctor plate 53, supported on the bearing 54, removes surplus paste from the roller, the plate having the threaded bolts 55 thereon which are set by means of the nuts 56 journaled in the yokes 57 on the bearing 54.

A lever 58, fulcrumed on the bracket 59,

- has a yoke 60 which is engaged in the groove 7 of the collar 7 whereby the latter and the wedge are moved longitudinally of the shaft 5. The lever is elevated to move the wedge into the mandrel to engage the sheet 19 in the operation of rolling it and is lowered to withdraw the wedge from its engagement with the sheet after rolling. The withdrawal of the wedge causes the shoulder 18' to engage a plate 5 on the mandrel, whereby the latter is, drawn back againstthe action of the spring 11 and thebolts 14 are pressed back to eject the tube bystriking the bearing 4.

The lever 58 has the crank lever 61 fulcrumed on the bearing 62 and connected 20. The latter has journaled thereon a pulley 71 having a hub 72 provided with the teeth 73 which coaot with a trigger 74 adapted to rock on the pin 75 carried by the sleeve, the trigger being thrown out in the path of the teeth by a coiledspring 76 carried by the sleeve. A cam 77 projects from the trigger and is adapted to make contact,

disengaged automatically, the winding mechanism comes to rest, and the lever 58 is depressed to move the mandrel longitudinally to effect the ejection of the tube.

The revolution of the shaft 5 revolves the shaft 36,- through the intermediate mechanism described, and causes the cam 44 to liftthe slide 42 and the presser bar 41 just before the end of the sheet 19 reaches the roll 37. The slide and presser bar are held elevated by a bar 78 fixed thereto which engages the top of a trigger 79 adapted to rock on the bearing 80. To disengage the trigger 79 from the bar 78 and permit the presser bar to fall, a tooth 79 is formedon the trigger and engaged by a toothed wheel 81 journaled'in the bearing 82, the wheel 81 being turned by a ratchet wheel 83 fixed thereto. This ratchet wheel is acted upon by a spring pressed pawl 84 which reciprocatesin a socket .85, the latter being fixed to the lever '58 by the fulcrum pin 58 thereof. Consequently, on elevating the lever 58 the wedge 18 is movedin to engage the sheet 19 to the mandrel 8, the bolt 68 is withdrawn from the path of the clutch trigger so that the clutch can engage to revolve the mandrel, and the ratchet wheel 83 is revolved to revolve the wheel 81 .and disengage the trigger 79 from the arm 78 so that the presser bar can drop upon the sheet to hold it against the paste roller 37 to effect the desired application of the adhesive.

Having described my invention, I claim: 1. In a machine of the character described,

a revoluble shaft, a mandrel revolved thereby, mechanism carried by said mandrel for engaging therewith a blank sheet to be wound thereon, mechanism carried by said mandrel for ejecting a tube therefrom, a

In witness whereof I have hereunto set my name this 14th day of July, 1909, in the presence of the subscribing witnesses.

JOHN NAZEL.
